Incremental-cooperative strategies in combination of adaptive filters

A new topology for combination of adaptive filters is proposed. Based on incremental strategies, the standard convexly combined parallel-independent filters are rearranged into a series-cooperative configuration without changing the computational complexity. Two new algorithms are derived from the new topology. Simulations in a stationary system identification scenario show the superior performance of the new algorithms.
